SPINNING AND WINDING APPARATUS:

Specification of Letters Patent.

Patented Oct. 10, 1916.

Application filed December 4, 1913. Serial No. 804,753.

a To all whom it 'may' concern.

Be it known that I, CHARLES W. HUBBARD, a citizen of the United States, residing at Weston, county of Middlesex, State of Massachusetts, have invented an Improvement in Spinning and Winding Apparatus, of which the following descrlption, 1n connectn with the accompanying drawing, is a specification, like characters on the drawing 10 representing like parts.

In my Patents Nos. 795,981 and 795,982 dated August 1, 1905, I have illustrated and described diflerent embodiments of a spinning and winding apparatus which is con- I 5 structed to lay the yarn or thread in transverse layers across the end of a thread mass. 7 The devices shown in said patents comprise a rotary support for the thread mass on which the thread mass is built up, a windi ing or thread-laying plate by which the yarn or thread is compactly laid on the end of the thread mass, a yarn guide which gives the yarn or thread a traverse, and means for rotating the yarn support and winding plate at different speeds thereby to cause the One of the features of my present invention relates to the manner of supporting and operating the yarn guide by means of which the latter will have a freer action. Another feature relates to an improved device for positively drawing the yarn from its source of supply and delivering it to the winding member, and other features of the invention relate to details of mechani- 46 cal construction, all as more fully hereinafter set forth and then pointed out in the appended claims.

Referring to the drawings wherein -I have illustrated my invention: Figure 1 is a sec- 60 tional view showing a portion of a spinning frame and one of my spinning and winding devices. F 2 is an enlarged ertical sectional view through one form of ,my spinning and winding device on the line e-e, Fig. 5. Fig. 3 is a section on the line acm,

Fig. 9 is a sect10n on the line bb, Fig. 7 looking downwardly. Fig. 10 is a plan View of Fig. 7. F g. 11 is a section'on the line dd, Fig. 8. F1g. 12 is a detail of the thread guide shown lliFlg. 9. Fig. 13 is an'enlarged sectional view through bearing plate at the upper end of the cage.

The devices shown in the drawing embody the main features of the devices shown in my aforesaid patents, that is, a rotary thread-supporting member, a winding member, means for rotating the winding and thread-supporting members at different speeds, and a thread guide for-giving traverse to the yarn or thread as it is laid on the thread mass. The thread-supporting member is herein shown as in the form of a plate 1, which'will preferably be supported in a basket or cage 2, within which the thread or yarn mass 3 is built up and which is herein shown as formed of longitudinal members 96 which are connected by bands or hoops 97. This cage 2 with its thread-supporting member 1 is shown as detachably secured to a hollow spindle 4, having a pinion 5 thereon which meshes -with and is driven by a driving gear 6.

The winding member includes a winding or thread-laying plate 7 which rests on the upper end of the thread mass 3 and is rotated relative thereto to cause the thread or yarn to be wound 'or laid on the thread mass. This winding member 7 is driven from a spindle 9 which extends down through the hollow shaft 4 and has a pinion 11 thereon which meshes with and is driven by the gear 12. The gears 6 and 12 have a different number of teeth thereon and the shafts 4 and 9 will, therefore, be rotated at different speeds. This causes a differential movement between'the winding plate 7 and the thread mass which causes the yarn or thread to be laid on the thread mass, all as described in said patents. The lower end of the spindle 9 is journaled in a;bearing 92 and the upper end of said spindle is journaled in a bearing carried by the cage at the upper end thereof, the construction being such as to permit the cage to be removed from the spindle.

. In the preferred embodiment of my invention the bearing for the upper end of the spindle is formed in a bearing plate 98 which is detachably secured to thecage and which is provided with a bearing for centering the cage. This bearing plate 98 is shown as having a bayonet joint connection with the top ring 97 of the cage so that byv giving the plate a slight turning movement relative to the cage, said plate can be unlocked and removed from the cage. This bearing plate 98 is provided with a spindle which is rotatably mounted in a bearing 93 carried by the framework 94. Said spindle 100 is also capable of being moved longitudinally in the bearing 93 so as to permit the bearing plate 98 to be raised from the cage as will be presently described. This bearing plate is also provided in its under side with a recess 101 in which the upper end of the spindle 9 is received, said recess forminga bearing for said spindle.

The bearing 93 is preferably secured to the frame 91 in such a way as to permit it to be moved out of the way whenever the cage is to be removed from its support, and this can conveniently be done by pivotally connecting said bearing to the frame as shown at 95, thus permitting the bearing to be swung upwardly into the dotted line position. The cage 2 is detachably secured to the hollow shaft tby means of apin-and-slot bayonet joint as shown at 89 so that said cage can be readily removed by merely moving it slightly and lifting it off of the shaft. Whenever the cage is to be removed the bearing plate 98 is first unlocked from the cage and is then raised up in its bearing 93 to clear it from the upper end of the spindle 9 and the bearing 93 may then be swung upwardly into the dotted line position, after which the cage can be disconnected from the gollow shaft 4 and removed from the spin- The spindle 9 may be made in one piece or may be made in two sections detachably secured together. The latter construction is that which is shown in Fig. 1, and the joint between the two sections of the spindle is shown as situated within the sleeve 4:. Where this construction is provided, the upper portion of the spindle can be removed from the cage and thread mass after the latter has been completely wound before the cage is removed from its support, if desired. Where the spindle is made in twosections, any suitable connection may be employed for detachably uniting the two sections,that

herein shown being in the form of a pinand-slot bayonet joint 88.

' The winding head, which includes the winding plate 7 above referred to, comguide.

prises a central hub or sleeve 13 which telescopes over-the spindle 9 and which is connected thereto so. as to rotate therewith, while being capable of moving longitudinally thereof. This can conveniently be provided for by making the spindle with a longitudinal groove 14 in which is received a. pin or feather 15 extending from the bushing 13. The winding plate 7 is rigid with the sleeve 13 and said sleeve also has secured thereto a head plate 16 which carries the tension and feeding device hereinafter described and which also sustains the differential gear for operating the thread 80 In the embodiment shown in Fig. '2, the head 16 has associated therewith an internal gear 17 which is driven by the cage or basket 2, .said gear having a projection 18 extending therefrom which engages one of the arms 96 of the basket 2, so that the rotation of the cage or basket will be transmitted to the gear 17. 19 is another internal gear loosely mounted on the head plate 16 and operated from the gear 17 through differential gearing so that the gear 19 has a slightly greater or slightly less speed than the gear 17 as desired. This gear 19 has connected thereto and operates the cam plate 20 by which the thread guide is given its traverse. The gears 17 and 19 have a dif ferent number of teeth and both gears mesh with a gear 21 loosely mounted on a stud 22 carried in the head 16. The head 16 is driven from the spindle 9 while the cage 2 will rotate at the same speed as the tubular shaft 4. Since these two shafts 4 and 9 are rotated at different speeds, itfollows that the head 16 will have a different speed of rotation from the cage and the thread mass. The cooperation of the gears 17, 19 and 21 causes the cam-operating gear 19 to have a faster or slower speed than the gear 17 dependent upon whether the gear 19 has a less or greater number of teeth than the gear 17.

In my prior patents, the yarn guide traveled back and forth in a guideway and received its reciprocatory movement directly from the cam. In the present embodiments of my invention the thread guide is mounted on a swinging member which has a free'swinging movement, the operation of which is determined by the cam 20. In Fig. 2, the thread guide is shown at 23 and it is sustained by an arm 24 pivoted to the head plate 16, at 25, said arm-being herein shown as provided with a roller 26 which engages the inner periphery of the cam 20. This thread guide travels back and forth in a slot or opening 27 formed in the winding plate 7. The cam 20 acts to swing the arm 2 1 and thread guide 23 inwardly toward the axis of rotation and a suitable spring device is employed to give the arm its movement in the other direction. In the illustrated embodiment of the invention this spring device is shown .as a coiled spring 28 situated in a recess 29 in the plate 16 and acting against a plunger 30 which engages. an arm 31 rigid wit hthe stem or'arm 24. Any otherv suitable spring mechanism for accomplishing this purpose might be used, however,

without departing from the invention.

In my former patents the yarn or thread passes from its source of supply directly to the thread guide and the winding plate and as a result the tension which was placed on. the yarn was due to the drawing action resulting from the relative movement between the winding plate and the yarn mass.

This produced more or less uneven tension on the yarn because of the varying position of'the thread guide. In my present invention I have provided means intermediate of 0 the source of supply and the'winding plate which acts on the thread or yarn and operates to draw the yarn from its source of supply with an even, steady motion and to deliver the yarn to the thread guide at a uni- 5 form speed. I find that by means of this construction the yarn can be laid more evenly and uniformly. and with less liability of breakage than with the construction illustrated in my patent. This yarn-drawing de-' 2 vice comprises a plurality of positively driven grooved rolls around which the yarn orthread passes and which are somewhat in the nature of capstans, and twopositively driven flat faced rolls between which the -yarn is .fed. This construction is perhaps best seen in Figs.3, 5 and 6uwherein 31 and 32 are two shafts journaled in the head block 16 and carrying gears 33 and 34 respectively that mesh with a gear 35 which is rigid with the gear 21, it being remembered that the gear 21 is journaled on the shaft 22 carried by the head block '16 but meshes with the internal. gear 17 which is driven by the basket or cage 2. The differential move- 5 meet between the gear 17 and the head block 16 causes the gear 21 to rotate on its axis and the rotation of this gear is transmitted to the gear 35, and from the latter to the gear 33 and 34 and the shafts 31 and 32. The

0 shaft31 has fast thereon a double grooved pulley 36 and the shaft 32 has fast thereon a pulley '37, both of thesepulleys being sitif- I ated abovethe head block 16. The shaft 32 also has thereon a rolL38 'preferably having a serrated face with which coiiperates an other roll 39 fast .on'the shaft 40 journaled in the block 16 and provided atits lower end with a gear 41 that meshes with the internal gear 17 .The yarn or thread 8 is led from 9 the source of supply downthroughthe hollpw upper end of the spindle 9, and out "lthrough an opening in the side of said spinthence around the other pulley 36 and between the rolls 38 and 39 and from the latter to an aperture 43 in the block, 16 through which it passes to the thread guide 23.

The rolls 38 and 39 constitute presser rolls which grip the thread or yarn between them and which operate to hold the yarn taut about the pulleys 36, 37. These pulleys 36, 37 act somewhat as capstans and as they are positively driven they operate to draw the yarn or thread 8 fromiits source of supply and to deliver it to the thread guide 23. By means of this construction the yarn or thread 8 is drawn from its sourceof supply at a. uniform speed and any strain or tension incident to this 0 eration is taken entirely by the rolls 36, 3. and not by the thread guide 23 or the winding plate 7. The thread is thus laid ,on the thread mass under a constant tension and there is no danger that it will become broken 'by strain or. tension that is put thereon by the winding plate. I Will preferably mount the shaft 40 in a swinging member so as to permit the roll 39 tobe moved toward and from the roll 38 thereby to facilitate the threading up of the machine. As herein shown the shaft 40 is rotatably mounted in a bearing 44 carried I by a swinging arm 45 that is mounted on the hub 13 and is adapted to have a swinging movement thereabout.

46 is a spring carried by the block 16 and acting against the plunger 47 which in turn has engagement with the arm 16, said spring 46 serving to yieldingly hold the roll 39 in engagement with the roll 38. The roll 39 is shown as provided with the extended hub 48 which provides a hand-hold, by which the member 45 can be moved to separate the roll 39 from the roll 38.

In the embodiment of the invention shown in Figs. 7 to 12 the thread guide swings in a horizontal planeand the cam for operating the thread guide is inclosed within the winding head. In other respects, however,-the construction shown in said Figs. 7 to 12 is substantially like that in 20 'for operating the thread guide. "This cam 20 is shown as located above the lower. 2 plate 51 and as sustained by an annular rest 52 carried by the plate In this embodiment the gear 19 is supported by the cam plate instead of supporting the cam plate as shown in Fig. 2. The differential gearing i "dle, thence down through a guide eye 42 and the feed device of Figs. 7 to 11 is the same as shown in Figs. 2 to '6. The thread sustained by the head 16, thence around one v guide in Figs. 7 to 12 is shown at 230 and of the pulleys 36, around pulley 37,

it comprises an eye or tubular member carried by an arm 56 which is rigid with a shaft 57 mounted in the bottom plate 51 and the winding plate 7 as shown in Fig. 12. The shaft 57 has rigid therewith an arm 58 carrying a roll 59 which engages the periphery of the cam 20, said roll being held against the cam by the spring 60. i The thread guide 230 plays-in a slot 61 formed in the winding plate 7 and this slot is slightly curved as seen in dotted lines 9 to conform to the arc of movement of the thread guide 230. 62 desi nates a guard finger carried by the plate the object of which is to prevent the thread or yarn from being thrown beyond the outer limits of the plate;
